12 Psi, Stock MAP. Am i OK?
 

i read that 11-12 psi is all the stock map can handle, so im wondering with the stock evo wastegate running 12 psi will i be alright or will it sometimes not read like during spikes?

It will be fine as long as you tune it with a wideband. Although the stock map is only good until ~11.5 psi, it will just read the last column of your maps if you boost above that. Basically, just make your last column a bit richer to make up for that 0.5 psi. You're barely past the limit, so there shouldn't be a problem hitting your target afr on 12 psi.
